Multi-Game Sites
Neopets (www.neopets.com)
A fun site that has it all! Adopt a pet and play versions of classic games to win neopoints and items to care for it! Highly addictive and highly cute. 100% PG, but don’t let that stop you.
AddictingGames (www.addictinggames.com)
A game site with a little bit of everything, ranging from the first-time developer to the expert, super-cute to the super-violent (against stick figures, mostly). Lots of fun games, but a warning: some of these may contain violence and teen situations.
Online RPG
RuneScape (www.runescape.com)
While you do have to pay for some content, the rest of RuneScape is completely free, and a lot of fun.
